At her request, the Emperor gives the aristocrat over to Shanyin for her pleasure, setting off a power play of sensual torment and dominance between them. Trapped in Shanyin’s harem for ten days, will the proud Yuan surrender to his own dark desires, or will he turn the tables on the seductive princess?
